  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Hot Mirror - IR Which one?

Just to reiterate off axis color shifts are a certainty with dichroic filters. Our Filters have no color shift and are an excellent choice when used properly. Our filters are NOT dichroic. The Pancro single layer, alloy coating is highly efficient, durable and presents a very favorable asthetic vibe! Many seasoned DP's as well as up and comers are currently producing amazing results with our IR+ND's and other product lines. The most visible being our recent Emmy nod for contributions to Adam Beckmans 09 win using our filters. Bottom line-they produce results! Also, if you want to see a clip using the IR+ND featuring one of the most talented cinematographers on the west coast, go to our site and click on the link from our homepage. www.pancro.com
 
I don't doubt that the Pancro's are the best optically. I have to say I'm unfortunately in the camp that has had the ghosting effect and this is with using them in the proper stacking order. I've often wondered if it was light leaking in to the mattebox. But it happened on a RR mattebox, as well as LMB-5 and MB-20. It's happened with Nikons and with RED Pro Primes. I'm afraid to use them in situations where we don't have a 17" or larger monitor.

Is it possible that the instances where we have been seeing the ghosting is just a lack of proper sealing on the matteboxes? Is it just stray light getting in there and wreaking havoc?

I think they are great filters, and want to use them with full confidence. If someone can go into more detail about why this ghosting would occur with proper stacking order, the filter facing the correct direction, and a professional mattebox holding it, that would be very helpful. I can't for the life of me figure out why it's happening.

And wondering if anyone can respond to Stephen's post above about Nikon and Canon lenses being particularly bad with the Pancros. That doesn't seem to make any sense that still lenses would be more prone to this. Am I missing something there?

Thanks!
 
Hi James,
You resurrected a thread from over 2 yrs ago. I can't remember when MX became available, but I think at this time most cameras were M sensors. MX changed things a bit and I seem to remember some guys selling their Hot Mirrors or IR filters after MXing their cameras. Can anyone direct this to a current ND filter reccomendation for Epic / Scarlet / MX sensors?

Hello Jeff.

I'd like your advise if you don't mind. I have the pancro IR+ND mirror set, but I have been using them with my canon primes and I do get once in a while the ghosting image, specially if mixed with black pro mist. Because of that reason I have been thinking to go for the Tiffen.

Because of economy (money and filter trays) I'd like to get just one set of NDs, same as the ones I have of Pancro.

Do you think these filters would work better and if placed carefully it would improve the ghosting image in relation to the Pancros? Thanks a lot Jeff, you're always of great help.

Rossco tru-color has not failed once, and be combined with any ND, and is cheap.
 
@LKamak I have 3 mx cameras and they still require hot mirrors above ND 6 - Also up around nd 1.2 or more then the hot mirrors tend not to work as effectively. In short IR contamination still creeps in - which is a drag. I was wondering if anyone had any thoughts on the deep cut hot mirrors?
 
I do not know why the Canons and Nikons ghost with Pancros, but it's a very serious problem. It is not a light leakage problem, because we can go from ghost to no ghost strictly by replacing the Pancro filters with the Formatt filters.
